One of the great cons. Dose nothing for the intake system , how could it ? A small amount of hydrogen gas fed into the intake along with air. Good honest video as always.

The last inlet manifold that I found clogged up with oily carbon (a 2015 Mini) i had to remove the manifold and clean it out with various aerosol solvents and a tooth brush and it was still a bugger to get clean so I'd be amazed and interested if one of these machines could to the job. Also keep up the good work Jimmy I find every video really interesting and informative.

I did the carbon cleaning on my 320d 230k km and it made a nice improvement. How you did the procedure is not the right way. First of all for €85,- it does a very good job. The engine needed to be running 45 min on stationair idle and the right amount of hydrogen mixture. When you rev the engine you pull most of the hydrogen direct through the engine and it burns away. You want to have the hydrogen gas as long as possible in the intake manifold to settle in the carbon. Only rev a few time between 2000-2500rpm to open the egr valve. After the session you go drive for at least 30 min on normal driving. After a time the engine starts running better and better even after two weeks i feel improvement. Of course this will not make it clean as new but it is worthy and worked for me.

Top man, you have proved what I thought when looking into this… Basically you can’t beat hours of labour, removing it all and good old fashioned elbow grease.(sorry to say) As far as cleaners go.. I use a good TFR(neat) apply.. Let it soak in!! Power wash off.. Repeat several times till your happy.. I’ve got parts back to nearly new looking this way. But it takes hours… Not good financially for the customer but the Job is done. Keep up the good work ❤

"A fool is easily parted with his money"

I had my Citroen C4 Picasso 1.6 THP from 2011 with 210.000 miles carbon blasted, and i must say it runs like new again No stuttering during driving.and uses less fuel now

Empties your wallet faster than emptying your engine.

"That is the only one people'd actually be interested in" People who know how recirculation works also know that any exhaust product (be it co2, methane, or anything) would get cooled back before it may enter the intake manifold. This is logical, not only for performance reasons, but also that many if not most recent cars have their intake manifold out of plastic (hello BMW!). Any combustion there would be a fatal error - one that sadly we do see from time to time on videos.

As far as i'm aware HHO cleaning is more for the Inlet and Exhaust valves as opposed to EGR as the Hydrogen has a more complete burn than normal fuel and this with the water is how it is cleaned by the time it gets to EGR will just be water so will do nothing.

HHO Carbon cleaning is more of a maintenance for EGR valves as it helps to keep the engine running more efficiently and removes carbon from the hot side of the engine. Generally most of the carbon oily gunk built up in the egr is from the breather system and exhaust gases baking it on 👍🏽 The proof in the pudding is a test drive of the car after the cleaning. The engine runs smoother - quiter and more responsive on most cars. Been doing carbon cleaning for around 4 years now never have I said that the processes cleans the egr or DPF actually blocks the DPF slightly due to the soot releases from the engine 😅 I always apply a cleaner for the cold side of the engine which helps with oils and gunk buildup from the breather system. Since using the cleaner it gives much better results 👍🏽 You see a lot of cowboy Carbon cleaners who post pictures of walnut of media blasting intake results 😂 There’s two types or carbon cleaner you just need to find the right one 👍🏽

I don't think it's hydrogen coming out of the machine. If it was, you will be able to hear a difference in the sound from the engine when you inserted the hose. (Hydrogen is a flammable gas so you should hear a difference in the revs when the engine gets more combustible material put in)

You are 100% right like I said on the last video hho will do nothing for the inlet side hydrogen has no cleaning properties what so ever but once it's burnt it goes back to water and oxygen so the water has a steam cleaning effect on the pistons and combustion chambers but will take a long time for any effect We have had a carbon cleaner for 2 years now and I have yet to see it fix a problem don't waste you're money the customers will just come back and accuse you of ripping them off as it didn't fix the car

Decent bloke. Knows his stuff.

Let's be fair, when we saw inside before the procedure started that thing was caked to death. No amount of Hydrogen gas being lightly flowed through was ever going to remove that! Unfortunately, the only way you're getting rid of that shite is to strip and painstakingly clean it out with elbow grease and many solvents. But really good video and super honest. 👍

Jimmy, if you've followed the manufacturers recommendations and you're not happy with the clean, then it's a null brainer. I do agree, it doesn't work. After an hour I would expect the internals to be minted. So, now we've all seen how mucky it is in there, when are you doing the walnut blasting video?

It might well be the case where someone has proven that HHO breaks down carbon and the more shady opportunists have made cheap HHO generators at a huge markup plus misleading marketing to make a quick buck. The only way I can see this working is if you drive around for 100s/1000s of miles with the generator permanently hooked up and then compare the before and after pictures. So basically this 'idea' has no real real world application in the motor trade whatsoever.

How about vapor ? Have you consider testing. Since vapor is low quantity and it can be compressed, it doesnt give hidrolock problems.

I’m sorry but my brother had this done on his land rover cost him a lot of money , a lot of bs ,I look forward to you doing this with a chemical solution, love your videos 😊👍❤️

I used an HHO machine that I made on my car along with using 2 secret products. I changed the spark plugs too and use 1 particular performance chip to have absolutely insane performance. 27 year old camry drives like literally brand new. My exhaust pipe has black stuff (and white) all over it and little puddles would form under the tailpipe.

The only way is walnut blasting with removing the intake. Started doing it in the 1980's. The carbon is too tough remove.

Buddy I do very similar work to you and you seem to have my solution every time. Thanks for all your effort and sharing your work . If you're ever in Manchester... 1:23

Its snake oil that service. There's only 1 real way to clean that properly.

I think the main problem was you were a little over 2300 rpm, a turbo actually spools up somewhere between 2500-3000 rpm, running the car back at idle then it allows things like the dpf to clogg back up due to it being closer to the car thinking it is running around town. it was a little cleaner on the 2nd look, no you shouldn't take it as high as more than 4000 rpm, while does heat up the engine as you know it also increases wear over time, but the more you can turn the engine over moving components in the engine the more chance of clearing the loose dirt on moving parts. personally never tried HHO Hydrogen so only going on my mechanic skills while dated are still relevent. but yeah nothing will actually beat a good clean by hand etc. redex has given me the most success for a car that was pre-igniting because of carbon build-up/cheap petrol, and not harmed using it on a diesel engine, but when it comes to carbon like I said nothing will get it 100% clean no matter what they say on the tin, just reduces the chance of build up over time. and I think your results from this test, and possibly other tests have shown that.

it's a shame this doesn't work - i was considering getting this done after seeing terra-clean done on wheeler dealers but sadly this video does seem to show that it is all just snake oil

All i can say is, Something Worked on my 2016 Peugeot Expert 2.0hdi with 175k on it. It wouldn't Rev past 3000....Did this and it revved freely. The real question for me is why didn't it rev and what cured it?

Don't you spray dpf cleaner into intake to clean your van's egr? Wouldn't it work on the Volvo?

Just another gimmick Jimmy to fleece folks.

Those d5's only tend to clog up by the EGR and local to the flaps and inlet ports. They're pretty good. Ended up disabling my EGR.

I watch your videos with great interest. I you had a new diesel car/van and it was a "keeper", would you use a quality diesel fuel additive with every tank full to reduce carbon over time? Is diesel fuel additive a myth? Many thanks.

Remove the manifold and use petrol to clean it up, works a treat but don't spray it in when it's on the vehicle you will blow the motor

I'd stick with walnut media blasting for carbon cleaning

Excellent. I hope the bloke from Bodgit & Leggit watches this video. He got well out of sorts when I suggested he was a conman a few years ago with his machine.

200k miles worth of baked on gunk, would we see better results on a lower mileage engine, with this being a preventative measure and not the cure?

You have exposed an industry, shame on launch, shame on the cowboy’s fleecing the general public. Your a brave man to highlight this. You have nothing to apologise for jimmy, the charlatans who peddle this snake oil of a business should be ashamed. The correct way to clean a DPF is the way manual way you’ve been doing it on your videos for years. Good video ❤

Strange, I got my 3.0d a6 with about 140k on the clock done along with a friend and his 1.9 golf with half the miles. He wasn't sure if it done anything, mine was a notable improvement straight away in mog and responsiveness

Have always said it is snake oil. Only way to clean that inlet and egr is by removal and physical cleaning.

I was always made to think that hydrogen attaches itself to the carbon molecules and degrades them over time. Not an instant fix. The the only way you will clear the carbon immediately is with an invasive chemical clean or a walnut blaster.

I saw at a BMW dealership workshop they decarbonize using walnut shells. Test this method.

I had egr issues for over a year and I tried everything including this. Nothing works. The only thing that worked was to take the egr off the car and manually clear it.

the only thing hho will clean is the combustion chamber and it takes ages not an hour but driving a car with a hho cell on it, when you dissasemmble and engine that runs a hho cell its absolutelyspotless inside like it was just assembled after a rebuild, hho when burnt produces water vapour that cleans thr engine thats not the goal its just a bonus, weve run hho cells since 78 for better economy, it makes a very good difference on "old" school desiels .

Thank you for your honest video. Greetings

Jimmy, put the better diesel in or add 2EHN in the tank (same thing) amd more gets burnt at lower temp therfore less bulds up. A cheap water injection kit is supposed to work wonders with steam cleaning the back of the inlet valves, but I've never seen anyone like yourself prove that.

What do you mean, the exhaust manifold dosent really matter to you. If the exhaust manifold is clogged the car cant breath properly. Ive got a Diesel Dmax and inside that exhaust manifold is about 5mm of carbon deposits plus gunk. That 100% puts stress on the rest of the engine. Hence it needs taking off and cleaning...

I always worry about cleaning out Manafolds and egr the only way to do it is to remove them from the car carb cleaner and high pressure steam cleaner

The only think I could possibly think it would clean the exsorst valve in the engine but nothing else

well done for giving it another try.

Is this basically the same as the lads going round doing engine tune ups

I don't think that would clean my undies after a saturday night out let alone carbon from a inlet manifold.

what an honest review. Evening sesh on the O'Rileys channel 👍🚗👍

I have same engine and clean egr by hand every year, would love to find easier way to manage, so not looking good for me!!

one last test get a binbag fill the binbag with the outlet of the magic machine tie the bag throw a burning match at it big bang = hydrogen

This are ment To clean combustion area and exhaust. Not for intake cleaning so this test is not so good. We are allso now testing this machine but we are measuring exhaust pressure and making exhaust testing before and after. Not so big hope for this but have To test 😂

not enough of the cleaner really gets to the EGR as most of it just goes down the exhaust . waste of time

If had 100 percent hydrogen. Disconnected fuel. And rain on hydrogen it would work. God bless my friend. Its not a fail. Its a learning point. God bless

Jimmy you were doing it all wrong, num 1 car facing wrong way num 2 wrong colour car num 3 the sun was out, num 4 this only works on cars with less than 100 miles on the clock 😁

just wondering if you did take it out for a 30 min drive on motorway would egr look different as its more wet so to speak? cheers great video thanks

Not enough hydrogen to accomplish even an increased in valve temperature.

He says it doesn’t work, but he didn’t drive, if he says don’t work after a test drive then I wonder? It certainly removed the carbon from piston , valve seats, exhaust manifold. He should feel a smooth drive after cleaning.

Shame it didn't work would have been a easy way to do this I've only seen walnut blasting on videos the last time i had to clean a egr valve on a vauxhall i took it off used spray chemicals and a tooth brush I am always a bit concerned were all the bits go when cleaning the parts when attached to the engine

Be interested to see a water decarb on that Volvo. Probably too late now. U can buy a good quality spray bottle for a fiver, I’d sooner put water through than strong spray chemicals

My xc90 Egr valve is choked, after I’ve cleaned it om diverting it down past the turbo and Dpf back into the exhaust… the way Mercedes do 😎

Hi Jimmy, have you done a vidio using chemicals???? I have just done my 2012 Volvo V70 D5, using Mr Mussel oven cleaner (off the car) it was worse than yours and is now nice and shiney, what do you use???

It's not the strongest that survives, nor the most intelligent; it is the one most adaptable to change they say. Some people can't change, and hate to admit they have been tricked into a fake dream that this works. Lazy people that think they have a real skill. Send them a Pico Scope to use then they can be out fixing real problems. Good video Mr O'Riley, them things are just shit.

What was the yoke that edd china was pushing for diesels?

Thank you 👍🏻👍🏻👍🏻👍🏻

They have one of those machines where I work. The rep came around all full of how fantastic it will be.... it isn't. That machine was used maybe four times, now it's just a very expensive coffee table. the whole thing is just snake oil, money spent on a 'clean' is better off saved for maintenance or repairs.

Is volvo have good engines

i subscribed because you are honest, thank you

No matter what you do you will never please everyone, opinions are like arseholes everyone's got one. That machine is about as useful as a 1 legged man in an arse kicking competition.

i thought it cleaned the ports and injectors and valves

thank you teacher . my hydrogen machine cleans both the intake manifold and also that of the whole hot part. with 2 pipes and 2 different liquids, 1 pipe produces hydrogen and the other injects a liquid for washing the intake manifolds in impulses. air solution❤

Sorry boss but I'm gonna say that's an hour or 2 of Ur life Ur not getting back but at least I no not to go down that root on my Mazda 2.2 skyactive fooking cars ayy gota love umm, new sub to your channel and I'm liking it a lot KEEP UP GOOD WORK LAD thumbs up👍👍

Hm, you are don't know what about you talking and what you doing. HHO gas can't clean inlet manifold, I don't know why you test this? HHO gas can clean combustion chamber and exhaust, and this give you effect in performances, engine working and lifetime (and other parts, EGR valve, turbo, catalisator, and particle filter) If someone claiming that HHO carbon cleaning clean inlet manifold, there are two possibilities: 1- he laying, and 2- he use some chemicals for manifold cleaning (but I'm not sure about results because I have no experience with this). And just to know, this black HHO machine is very week 😄 Can do something, but need much more time. You need 220V machine, about 2000W minimum. And you put HHO gas hose on wrong way, around hose air enter manifold, after MAF sensor, that's all no good. You need good machine and to testing how was before and after: exhaust gases, injectors parameters, noise, acceleration, power and tork. But those tree last things cant be easy measure because no every time big changes. You must to believe to yourself feeling, and know how to test. Don't test in high rpm, but test in low rpm and big load. Everything you want to know, you can ask me, because I developed this process.

Build a machine that sprays carbon cleaner at 4 mbar

Does it cleans dpf atleast or not?

Unusual spelling for o rielly

This is what happens when you don't use the right hydrogen technology just by watching the video the machine is not making the right hydrogen!

Why not make a small hydrogen generator and permanently fix it. Find out in you tube. ....your car will be hybrid. Saves fuel.

If it has no effect on the pcv I am not diggin

snake oil my friend

Tried ur best pal

Very interesting I learnt the other day hydrogen implodes when egnited and sucks piston up to run. Mike

oil catch can......

Potassium Hydroxide the key mate for carbon cleaning not Hydrogen or any other rubbish 😅

Mmm 😢

Could have saved a load of time by teaching yourself how hydrogen and carbon react with each other. Browns gas FTW!!!

That machine doesn't work but that doesn't mean all hydrogen cleaning machines don't work. Plenty of data to show they do work.

One honest grease monkey here 💪

Quack machine. Scrap it. Ignore the naysayers.

So scam ! Sad

Lol

It does work, mate ! Trust me ! HHO burns at higher temperature/explosive! Can damage exhaust valves, and you'll notice knocking noise ! It will clean the exhaust system, not the intake ! You've done this video for ,,, 😢 click bait, ,,,
